Operation steps
Use USB to RS422 serial line to connect PC and laser.
Open the laser host computer and open the serial port.
Connect the laser power line and turn on the power supply.
Turn on the external enable switch of the laser and power on the laser.
Check the status and current temperature of the laser through the host computer, and start the temperature control (the red box button below).
Note: Before starting the laser, it is necessary to start the temperature control first and wait for the temperature to reach the set value.
After starting the temperature control, wait for the temperature to reach the set temperature (the default value is 55°C, do not change it at will). The red box is the real-time temperature of the temperature control.
After the temperature is reached, click the "Emit laser" button to launch the laser.
After working, please turn off the power
Parameters Description
As shown in Figure 4.1, the host computer interface includes laser irradiator parameter setting and data
display.Laser triggering mode (internal triggering, external triggering), encoding mode (precise frequency, time encoding), working time, driving current, etc. can be set.
Debug mode: no limitation on the working time of laser light emission
Trigger mode: "external trigger" means the use of external differential signal to trigger the laser, the light pulse frequency follows the frequency of the external signal. "internal trigger" means the trigger signal is generated by the information processing board.
Q-switching delay: the delay between Q-switching signal and LD drive signal, whose value and LD drive pulse width affect the laser energy. Generally, when the LD drive pulse width is 230us, Q-switching delay is 235us.
LD drive current: the change of drive current will cause the change of laser output energy. The larger the current, the larger the output energy. Generally, the LD drive current does not exceed 120A. To change the LD drive current, the value of the current needs to be set first, and then click the laser gear position 0, and the current binding is completed.
LD drive pulse width: signal pulse width, generally 230us.This value is the default, remain unchanged.
100mJ laser ranging target designator only single driver, the LD2 parameter setting is invalid.
The working time indicates the laser light time, when the light time reaches the set value, the laser stops output, the laser ranging target designator starts to enter the rest state, after the completion of the rest automatically light, laser ranging target designator light 1 times increase 1 times the cycle, when the cycle times reach the set
number of cycle times, no longer cycle light.
The range finding part of the parameters only range finder, the closest range gating and the furthest range gating
these three parameters.
BUILT-INCODINGDEFINITIONS
Precise frequency
The pulse frequency of light emission. For example, if the frequency is set (bound) to 20Hz, the light emission frequency of the laser is 20Hz.
Time coding
Time coding consists of 8 time values and code length. The time value refers to the interval time between two
successive laser emission.For example, the 8 time values are 40ms, 43ms, 46ms, 49, ms, 50ms, 53ms, 56ms and
60ms respectively.If the code length is 3, the first 3 time values are taken to participate in the laser emission cycle, that is, the first and second laser interval is 40ms, the second and third laser interval is 43ms, the third and fourth laser interval is 46ms, and the laser interval time repeats the three time interval values.If the code length is 5, the laser interval time repeats the first five time intervals.
